Differential pressure controller HE 5420

digital

Measuring range 0...25 / 30 / 40 / 50 / 60 / 70 / 80 / 90 / 100 mbar 3-digit digital display of differential pressure Analog output 0(4)-20 mA 2 relay outputs (ΔP-alarm, ΔP-cleaning) Adjustments: lower und upper switch-point,ΔP-alarm-threshold Main supply 230 V AC, optional 115 V AC Versions: - PCB board, 107 x 107 x 42 mm (w x h x d) - DIN-rail-mounting, 111 x 111 x 55 mm - plastic housing, 150 x 200 x 101 mm Options: customized pressure measuring ranges The ΔP-controller HE 5420 is used for differential measure- and control functions in air pollution control systems. The controller enables a ΔP-dependend cleaning through activation of a lower and an upper switch-point and an alarm-threshold for supervising the maximal differential pressure (ΔP-alarm). The actual differential pressure or the switching points are displayed with an 3-digit digital seven segment display.
